<P ALIGN=CENTER>GNU GENERAL PUBLIC LICENSE<BR>
Version 2, June 1991</P>

<P ALIGN=CENTER>Copyright (C) 1989, 1991 Free Software Foundation, Inc.<BR>
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA<BR>
Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.</P>

<P ALIGN=CENTER><B>GNU GENERAL PUBLIC LICENSE<BR>
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</B></P>

<P>0. This License applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License.  The
"Program", below, refers to any such program or work, and a "work based
on the Program" means either the Program or any derivative work under
copyright law: that is to say, a work containing the Program or a
portion of it, either verbatim or with modifications and/or translated
into another language.  (Hereinafter, translation is included without
limitation in the term "modification".)  Each licensee is addressed as
"you".</P>

<P>Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the Program
(independent of having been made by running the Program). Whether that
is true depends on what the Program does.</P>

<P>1. You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you conspicuously
and appropriately publish on each copy an appropriate copyright notice
and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and give any other
recipients of the Program a copy of this License along with the
Program.</P>

<P>You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a
fee.</P>

<P>2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:</P>

<OL TYPE="a">
	<LI>You must cause the modified files to carry prominent
	notices stating that you changed the files and the date of any
	change.</LI>

	<LI>You must cause any work that you distribute or publish,
	that in whole or in part contains or is derived from the
	Program or any part thereof, to be licensed as a whole at no
	charge to all third parties under the terms of this
	License.</LI>

	<LI>If the modified program normally reads commands
	interactively when run, you must cause it, when started running
	for such interactive use in the most ordinary way, to print or
	display an announcement including an appropriate copyright
	notice and a notice that there is no warranty (or else, saying
	that you provide a warranty) and that users may redistribute
	the program under these conditions, and telling the user how to
	view a copy of this License.  (Exception: if the Program itself
	is interactive but does not normally print such an
	announcement, your work based on the Program is not required to
	print an announcement.)</LI>

</OL>

<P>These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.</P>

<P>Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.</P>

<P>In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of a
storage or distribution medium does not bring the other work under the
scope of this License.</P>

<P>3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:</P>

<OL TYPE="a">

	<LI>Accompany it with the complete corresponding
	machine-readable source code, which must be distributed under
	the terms of Sections 1 and 2 above on a medium customarily
	used for software interchange; or,</LI>

	<LI>Accompany it with a written offer, valid for at least three
	years, to give any third party, for a charge no more than your
	cost of physically performing source distribution, a complete
	machine-readable copy of the corresponding source code, to be
	distributed under the terms of Sections 1 and 2 above on a
	medium customarily used for software interchange; or,</LI>

	<LI>Accompany it with the information you received as to the
	offer to distribute corresponding source code.  (This
	alternative is allowed only for noncommercial distribution and
	only if you received the program in object code or executable
	form with such an offer, in accord with Subsection b above.)</LI>
</OL>

<P>The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to control
compilation and installation of the executable.  However, as a special
exception, the source code distributed need not include anything that
is normally distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the operating system
on which the executable runs, unless that component itself accompanies
the executable.</P>

<P>If distribution of executable or object code is made by offering access
to copy from a designated place, then offering equivalent access to
copy the source code from the same place counts as distribution of the
source code, even though third parties are not compelled to copy the
source along with the object code.</P>

<P>4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt otherwise
to copy, modify, sublicense or distribute the Program is void, and will
automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such parties
remain in full compliance.</P>

<P>5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying the
Program or works based on it.</P>

<P>6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.</P>

<P>7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.</P>

<P>If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.</P>

<P>It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.</P>

<P>This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.</P>

<P>8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License may
add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among countries
not thus excluded.  In such case, this License incorporates the
limitation as if written in the body of this License.</P>

<P>9. The Free Software Foundation may publish revised and/or new
versions of the General Public License from time to time.  Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.</P>

<P>Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation.  If the Program does not specify a
version number of this License, you may choose any version ever
published by the Free Software Foundation.</P>

<P>10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the
author to ask for permission.  For software which is copyrighted by the
Free Software Foundation, write to the Free Software Foundation; we
sometimes make exceptions for this.  Our decision will be guided by the
two goals of preserving the free status of all derivatives of our free
software and of promoting the sharing and reuse of software
generally.</P>

<P ALIGN=CENTER><B>NO WARRANTY</B></P>

<P>11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
PROGRAM IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</P>

<P>12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.</P>

<P ALIGN=CENTER><B>END OF TERMS AND CONDITIONS</B></P>

<P ALIGN=CENTER><B>HOW TO APPLY THESE TERMS TO YOUR NEW PROGRAMS</B></P>

<P>If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

<P>To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

<PRE>
<VAR>one line to give the program's name and an idea of what it does.</VAR>
Copyright (C) <VAR>yyyy</VAR>  <VAR>name of author</VAR>

This program is free software; you can redistribute it and/or

This program is distributed in the hope that it will be useful,

</PRE>

<P>Also add information on how to contact you by electronic and
paper mail.</P>

<P>If the program is interactive, make it output a short notice
like this when it starts in an interactive mode:</P>

<PRE>
Gnomovision version 69, Copyright (C) <VAR>year</VAR> <VAR>name of author</VAR>
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'.  This is free software, and you are welcome
to redistribute it under certain conditions; type `show c'
for details.
</PRE>

<P>The hypothetical commands <SAMP>`show w'</SAMP> and <SAMP>`show c'</SAMP> should show
the appropriate parts of the General Public License.  Of course, the
commands you use may be called something other than <SAMP>`show w'</SAMP> and
<SAMP>`show c'</SAMP>; they could even be mouse-clicks or menu items--whatever
suits your program.

<P>You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

<PRE>
Yoyodyne, Inc., hereby disclaims all copyright
